PULLEY.

SPECIFICATION forming part of Letters Patent'No. 278,425, dated May 29,1883. Application filed March 13,1883. (No model.)

To all whom it may concern:

Beit known that we, HARMoN H. FULTON and OLAFR. OLsEN, ofthe cityofIndianapolis, county of Marion, and State of Indiana, have inventedcertain new and useful Improvements in Pulleys, ofwhich the following isa specification.

Oursaid invention relates to that class of pulleys the web and rim ofwhich are constructed separately and afterward attached together; and itconsists in providing for such a pulley a web composed of corrugatedsheet metal. I

Referring to the accompanying drawings, which are made a part hereof,and on which similar letters of reference indicate similar parts, Figure1 is a side elevation of a pulley embodying our said invention; Fig. 2,a central vertical section of the same on the dotted line 2 2; Fig. 3, aview similar to Fig. 1, except that it illustrates an alternateconstruction,; Fig.4, a central vertical section of the same on thedottedline y 3 and Fig. 5, a detail horizontal sectional view, lookingupwardly from the dotted line as w in Fig. 3. I

In said drawings, the portions marked A represent the shal't on whichthe pulley is mounted; B, the hub;(), the web, and D the rim.

The hub B is mountedon the shaftAin the. ordinary manner, and, except inbeing corru gated to fit the corrugated sheet-metal web, is of awell-known form. The corrugations on one are formed to fit into those ofthe other, so as to clamp the web tightly when said web ThewobGismadeofany kind of sheet metal desired, a light, tough sheet-steel being'deemedpreferable. The-corrugations may be circumferential, as shown in Fig. 1,or radial, as shown in Fig. 2, or serpentine, as may be desired orpreferred by the maker of the pulleys,

it being obvious that nearly any form of corrugations will serve. ourpurpose of stiffen ing sheet metal so that it will be a fit material forpulley-webs, and we do not, therefore, desire to limitourselves in thisparticular.

. Therim D is an ordinary sheet or hoop metal rim, and is secured to theweb by rivets.-

Small angle-irons may be employed; or projections may be cut on the edgeof the web and bent each way, as shown, to take the place of theseparate angle-irons.

Having thus fully described our said invention, what we claim as new,and desire to secure by Letters Patent, is-

1. In a pulley, the combination, with the hub and rim, of a web formedof corrugated sheet metal, substantially as set forth.

2. The combination of the hub B, formed of A two parts with corrugatedfaces, the web 0, corrugated and formed to fitbetween the two parts ofthe hub, and the rim 1), secured to the periphery of the web tially asset forth.

In witness whereof we have hereunto set our hands and'seals, atIndianapolis, Indiana, this 10th day of March, A. D. 1883.
